To all whom it may concern:

Be it known that I, THOMAS D. W. PINCK- may, a citizen of the United States, and a resident of the city of New York, borough of the Bronx, in the county and State of New York, have invented anew and Improved Fluid Power-Transmltter, of which the following is a full, clear, and exact description.

The invention relates to couplings or clutches, using a liquid for effecting the coupling between a driving and a driven member.

The object of the invention is to provide a new and improved fluid power transmitter or clutch designed for use on automobiles and 'other power-driven vehicles and maohinesand arranged to insure the proper transmission of power from one member to the other.

In order to accomplish the desired result use is made of a revoluble casing and a paddle wheel therein, the casing being the driving member and the paddle wheel being the member to be driven, the casing being filled with a liquid and being provided with inwardly-dished ends and radial vanes on the said ends to impart motion to the liquid in an outward direction, toward the middle of the casing, and against the vanes of the said paddle wheel, the latter being intermediate the said casing vanes.

A practical embodiment of the invention is represented in the accompanying drawings'formi'ng a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a longitudinal central section of the fluid power transmitter; Fig. 2 is a transverse section of the same 'on the line 2-2 of Fig. 1; Fig. 3 is a perspective view of one of the paddle wheel sections; Fig. 4 is a side elevation of the power transmitter with the casing shown in section and the paddle wheel in practically dormant position; Fig. 5 is a side elevation partly in section of a modified form of the transmitter; and Fi 6 is a similar, view of another modifie form of the fluid power transmitter.

The closed casing A is secured to the driv- Speeifieation of Letters Patent.

tions A and A are curved inwardly toward each other at their outer ends, as plainly indicated in Fig. 1, and on the said ends of the casing sections are arranged radiallydisposed vanes D and D having their inner edges spaced apart so as to provide a central space E within the casing A and in which central space is arranged a paddle wheel F. The paddle wheel F is preferably made in two sections having webs F, F provided at their opposite faces with radially-disposed vanes F F of which the vanes F extend through radial slots F 5 in the web F while the vanes F extend through radial slots F in the web F When the webs F and F are in close proximity to each other, as indicated in Fig. 1, then the outer edges of the vanes F F are close to the inner edges of the vanes D and D, as plainly indicated in Fig. 1, that is, the vanes are in positionfor receiving the full impact of the liquid with which the easing A is filled. When the web F is moved outward away from the web F (see Fig. 4) then the vanes F, F are moved more or less out of action according to the distance the webs are moved apart. Thus when the web Patented Jan. is, was. Application filed March 10, 1913. Serial No. 753,249.

F 2 is moved into outer extreme position the bore in the hollow shaftG so that the shafts G and H rotate in unison but the shaft G is free to slide on the shaft portion H of the shaft H. The shaft G extends through a suitable stuffing box I held on the casing section A and on the outer end of the shaft G is secured a shiftin collar J engaged by a shifting lever (not s own) under the control of the operator for shifting the shaft G so as to move the web F toward or from the web F for the purpose previously mentioned. A spring K is coiled. on the inner portion of the shaft G and rests with one end on the stuffing box I and abuts with the other-end against the web F so as to norwith the machinery to be driven and the inner end H of the said shaft is journaled in a bearing A forming part of the section A of the casing A.

The operation is as follows: When 1t is desired to transmit power from the shaft B to the shaft H, the operator moves the shlft- -ing collar J outwardto draw the webs F,

F apart so that their vanes F, F are practically in dormant position. The radial motion givento the shaft B causes a rotation of the casing A so that the liquid therein is carried around by the vanes D and D and is thrown outward by centrifugal force and by the curved ends the liquid is thrown into the space E containing the paddle wheel F, but as the vanes of the paddle wheel F do not project the paddle Wheel remains dormant. lhe operator now gradually shli'ts the collar J inward so that the web F moves toward the web F to project the vanes F F beyond the outer faces of the webs F and F and when this takes place the liquid in motion comes in contact with the pro ecting ends of the vanes thus rotating the paddle wheel in the same direction in which the casing A is revolved. The radial n10- tion' given to the paddle wheel I. s transmitted by the shaft H to the machinery to be driven. By gradually moving the web F toward the web F more vane surface is presented to the liquid so that the transmission of power from the shaft 1) to the shaft H becomes gradually more powerful. When the web F touches the web F the vanes F F are projected to their fullest extent so that the vanes receive the maximum force of the rotating liquid.

It will be noticed that by the arrangement described the motor connected with the shaft B can be rotated with unvarying speed while that of the driven machinery may vary in its speed according to its \"arying load, and consequently all shock and jar 1s prevented and the motor can run its full efliciency.

When the power transmitter is used in automobiles and similar power-driven veliicles it is not necessary to change from a high to a low gear or vice versa as it is only necessarv to shift the web F toward or from the web F for a more or less powerful transmission of the power from the shaft B to the shaft H.

In the modified form shown in Fig. 5, the casing section A is provided on its outer face With a conical clutch member A adapted to be engaged by a correspondingly shaped clutch member L mounted to slide on the shaft G and provided with a shifting collar L engaged by a shifting lever (not shown) under the control of the operator for shifting the clutch member L in or out of frictional contact with the casing clutch member A, otherwise the construction is the saine as above described in reference to Figs. 1 and a, and further description is not deemed necessary.

In the modified form shown in Fig. 6 the outer portion A of the casing section is fashioned to provide a fly wheel for the easing A to insure steady running of the casing. I

Although the casing A is described as the driving member and the paddle wheel as the driven member it is evident that the paddle wheel may be the driving'member and the casing the driven member.
